Original Abstract

The paper deals with a development and application of the robust and flexible computational model of turbocharger rotor. In other words the Virtual rotor, includes models of radial floating slide bearings, axial thrust bearings and nonlinear rotor model. Theoretical backgrounds of the slide bearing computational models, based on the numerical solution of the Reynolds equation, are presented. The rotor is modelled as a flexible structure based on the Euler-Bernoulli’s beam nonlinear theory suitable for an effective solution in the time domain. There is also presented an application of multibody software for simulation of the turbocharger rotordynamics as a nonlinear transient dynamics problem. The simulation capabilities and possible results are demonstrated on the tractor diesel engine turbocharger rotor supported by fully floating ring bearings.

Keywords
